The time has come to replace the tires on my snelfiets. The Continental Grand Prix 4000s have been on it for 8400 km (5200 miles) over 14 years! It is very impressive they lasted this long, but besides visible wear I was beginning to feel a loss of grip when cornering on pavement.
They were yellow. I loved the aesthetics of this with the Lemond, but they felt more appropriate when I was among the fastest riders in most group rides. Today, thanks to some combination of age, waning commitment, and a different community, I am decidedly average in speed.
So, I now have placed black Specialized Roubaix Pros. They are so boring.
